A Toronto woman is suing Rogers Wireless Inc. for ruining her marriage.

Gabrielle Nagy, who subscribed to Rogers wireless services, requested her billing be addressed to her family home under her maiden name. When her husband ordered additional services — internet and cable television — from Rogers in June 2007, Rogers bundled Nagy’s billing with her husband’s.

Ms. Nagy’s husband realized his wife’s infidelity when he saw hours-long conversations with a particular phone number and confronted Nagy. The two are now separated.

Ms. Nagy is suing Rogers for $600,000, citing negligence and breach of contract.

“The defendant breached the said duty of reasonable care by acting in a manner below the standard of conduct expected from the defendant […],” says Nagy’s statement of claim.
